Question

I’m looking a way to get the following string using Xpath 2.0 only:

AAA-Site-1.test.com,BBB-Site-1.test.com

<SystemRoot SystemName='Xpath Test'>
     <SystemRoot SystemDomain='test.com' SystemName='AAA-Site-1'>
      <Product InstallDate='11/01/2012' ProductName='AAA'/>
    </SystemRoot>
    <SystemRoot SystemDomain='test.com' SystemName='BBB-Site-1'>
      <Product InstallDate='11/01/2012' ProductName='BBB'/>
    </SystemRoot>
</SystemRoot>

I tried concat and then string-join, but I get “too many values” …

concat(/SystemRoot/SystemRoot/@SystemDomain,'.',/SystemRoot/SystemRoot/@SystemName)

Is it possible to achieve by using XPath 2.0 only ?

Yes, this is possible:

string-join(/SystemRoot/SystemRoot/concat(@SystemName, ".", @SystemDomain),
            ",")
